Circuit/System Testing

WARNING: This page is about a different car, the 2008 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:
  • The PPS module
  • The SDM module
  • The PPS module harness connector
  • The SDM wiring harness connector
  1. Ignition ON, Verify the passenger air bag ON/OFF indicators illuminate.
  2. Ignition ON, use the scan tool and access the passenger presence system (PPS) menu. Retrieve the PPS DTC codes. Verify no PPS DTCs are set.
  3. Verify the correct PPS part number is installed in the vehicle.
    • If the wrong PPS was installed, replace with the correct PPS.
  4. Ignition OFF, disconnect the X1 harness connector at the PPS module.
  5. Ignition OFF, test for less then 5 ohms between the ground circuit terminal D and ground.
    • If greater then the specified range, test the ground circuit for an open/high resistance.
  6. Ignition ON, verify a test lamp illuminates between the ignition circuit terminal A and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal replace the PPS module.
  7. If all circuits test normal, replace the SDM.
